"It's changed a tiny bit," Theron tells Secret about her new life as a mom. "I now travel in a pack. Look, it's been amazing the amount of emails and congratulations. Everyone's just been so lovely. So it's been really nice."

When asked about which baby product she loves the most, the star takes a pregnant pause.

"Ooh," she says before offering an answer. "I gotta say, I didn't think I would be a fan of the swaddling"—that would be when you wrap your baby tightly in a blanket—"but the swaddling is pretty amazing."

She laughs, though, that "at first it looks like a straitjacket, and you feel like it's child abuse. But for some reason they just love it."

No doubt the star herself is also loving her best and most exciting role to date.
